To secure the fabric I use either the small binder clips or flat flower pins
the flower pins are also handy for putting a label on showing how much fabric is on the board. I also put my scraps that are too big to cut (for me that means anything larger than 10” in any direction) on boards and often there are multiple pieces of a single fabric on a board. In that case it’s really handy to have a label pinned on that shows how many pieces and size of each.
